BACKGROUND ART

As the market for electronic device applications becomes more active, alot of learning content is being developed in the form of applications.Conventional learning applications can provide an auxiliary role forlearners to easily access learning content by allowing video lectures tobe watched in the application, providing content for memorization, orproviding voice files.

Meanwhile, among learners, some learners aim to improve their overallperformance in a specific field, but learners will use learning contentto acquire a target score on a particular test.

Tests are designed to evaluate the learning ability and academicachievement of learners. Tests are generally composed of multiple choicequestions in order to secure standardization and quantification ofevaluation. All tests have certain patterns, and in particular, multiplechoice questions consist of patterned questions, called types ofquestions. Therefore, it is known to be a very effective learning methodto learn question patterns while solving many questions repeatedly.

Multiple choice questions are made up of text and examples, and somelistening tests are provided only with examples. Conventionally, it hasnot been easy to find such multiple choice question content inapplications. This is because it is not easy to display multiple choicequestion content including long text due to the characteristics oflearning applications, which are executed on an electronic device with arelatively small screen.

However, considering the purpose and effects of learning, it isnecessary to provide learning content by which a learner can repeatedlylearn multiple choice questions, even through electronic deviceapplications. Therefore, there is demand for a method of effectivelydisplaying multiple choice question content composed of text andexamples even on a small screen.

Method for Displaying Learning Content

Hereinafter, a method for displaying learning content according to anembodiment of the present disclosure will be described with reference toFIGS. 2 to 4.

FIG. 2 is a flowchart illustrating a method for displaying learningcontent according to an embodiment of the present disclosure. Thelearning content displayed by the method for displaying learning contentof the present disclosure may be generated by a device for generating auser interface screen, and may be displayed on a terminal by theexecution of an application program according to an embodiment of thepresent disclosure.

For reference, it should be noted that each operation of the method fordisplaying learning content described in this specification can besimultaneously performed, and as a result, a plurality of layers can besimultaneously displayed on one screen in a terminal.

Referring to FIGS. 2 to 4, in operation S110, a terminal displays textwith a group of questions on a first layer 100. The text with a group ofquestions refers to text corresponding to one or more questions. Forexample, one block of text can be presented in a language test and aplurality of questions can be presented in association with thecorresponding text. In this specification, the text associated with oneor more questions is referred to as text with a group of questions.

In operation S130, the terminal displays a first question cardcorresponding to a first question on a second layer 200. The questioncard may include one or more examples 210 that can be selected by alearner. The question card may include one or more examples according tothe type of the corresponding question, as shown in FIG. 4, or mayfurther include questions.

For example, FIG. 4 shows a question of selecting the appropriate wordto be inserted into the text. Accordingly, only words corresponding toexamples are included on the question card, but if the text is read anda question pertaining to the text is set differently for each question,a question corresponding to the corresponding question may be includedin the question card.

Next, when a continuous touch gesture in a touch input, such as a swipe,a drag, a double tap, a long tap, or a long press, is received in thesecond layer in operation S150, the terminal displays a second questioncard corresponding to a second question according to the touch gestureon the second layer in operation S170. For example, in the case in whichthe question card shown in FIG. 4 is a question card including examplesfor a question #5 135A, when the question card is swiped to the left, aquestion card including examples for a question #6 136A may be displayedon the second layer 200. If the touch gesture is an operation of swipingto the right, the terminal may switch the question card displayed on thesecond layer from the question card of the question #5 to a questioncard of a question #4.

Further, when the continuous touch gesture in the touch input isreceived in the second layer in operation S150 and the question carddisplayed on the second layer is switched from the first question cardto the second question card in operation S170, the terminal moves, inoperation 175, the text with the group of questions in such a mannerthat a portion corresponding to the second question in the text with thegroup of questions displayed on the first layer is positioned at thecenter of the first layer while operation S170 is performed.

For example, in FIG. 4, a question card #5 is currently displayed on thesecond layer, and therefore text corresponding to the question #5 isdisplayed in the central portion of the first layer 100. Here, when atouch gesture is input so that a question card #6 is displayed on thesecond layer 200 by the learner swiping the question card #5 to theleft, the terminal moves the text displayed on the first layer 100upwards so that a portion corresponding to the question #6 136A ispositioned at the center of the first layer.

Further, when receiving selection input for an arbitrary example fromthe learner in the state in which a question card #1 is displayed on thesecond layer, the terminal may display a question card corresponding toa question following a question #1 on the second layer. That is, whenthe learner solves the question card #5, the question card #6 isautomatically displayed on the second layer. At the same time, thecorresponding screen is switched from the text corresponding to thequestion #5 to the text corresponding to the question #6, and theswitched text corresponding to the question #6 is displayed at thecentral portion of the screen of the terminal. Accordingly, the learnercan solve the questions sequentially without any special manipulation,so that the learner's convenience can be maximized and the learner canfocus on the question-solving itself.

Meanwhile, as shown in 150A in FIG. 4, the terminal can display aremaining question-solving time in one area of the first layer. Mostexams are designed to solve questions within a time limit. The learnercan improve the speed of solving questions by checking the remainingquestion-solving time and training to solve questions within a timelimit.

In addition, when not all of the text is displayed on the screen at thesame time, as shown in FIG. 4, because the text with the group ofquestions is longer than the size of the first layer, the learner canmove the text with the group of questions by inputting a touch gesturesuch as touching one area of the first layer 100 and dragging or swipingthe text with the group of questions successively to the touch inoperation S300.

That is, when the touch input is received on the first layer, theterminal may display a scroll bar corresponding to the length of thetext with the group of questions on one area of the first layer, andwhen the continuous touch gesture in the touch input is received in thefirst layer in operation S300, the terminal may move the text with thegroup of questions displayed on the first layer according to thereceived touch gesture.

In addition, when selection input for all questions corresponding to thetext with the group of questions is received, the terminal may furtherinclude an operation of displaying a text or image corresponding to ananswer submission on one area of the first layer. For example, if thereis a total of 4 questions corresponding to one block text with a groupof questions and the learner inputs answers to all of the 4 questions,the text “submit answer” is displayed on the lower end side of the firstlayer as shown in FIG. 160A of FIG. 4. When the learner touches the text“submit answer”, the answer is transmitted to a server and the screen isswitched to a correct-answer confirmation mode. In the abovedescription, the case has been described in which a link pertaining to aquestion-solving time or to whether the answer submission is performedis displayed at the lower end side of the first layer. However, this isonly an embodiment, and a user interface according to the presentdisclosure creates a separate layer to display a previous menu, a nextmenu, time information, etc., on the created layer, which may varydepending on the setting of the user interface.

User Interface to Erase Example

Referring to FIG. 3, a terminal may receive input for an arbitraryexample from a learner in operation S210. When the input in operationS210 is touch input for erasing an example in operation 230, theterminal may perform erasure display on the example corresponding to thetouch input in operation S250. When the input in operation S210 is touchinput for selecting an example, the terminal may select the examplecorresponding to the touch input as the answer in operation S255.

Whether a touch input for an arbitrary example is determined to be aselection input or an erasure input in operation S230 depends on presetcriteria. For example, a tab or press for one area may be preset to bedetermined to be selection input and a double tap, a long press, orswipe may be preset to be determined to be erasure input, which may varydepending on the setting of a device for generating a user interface.

Referring to FIG. 4, when the learner performs a touch input forselecting an example A 210A, the terminal may select and highlight theexample A 210A as the answer, and when the learner inputs a double-tapoperation for erasing an example C 210C, the terminal may performerasure display by displaying a strikethrough on the example C 210C. Theerasure display may be performed via the strikethrough, blurring ofbrightness and saturation, shading adjustment, or the like. It is awell-known question-solving method to erase examples. According to thepresent disclosure, the conventional question-solving method may beimplemented as a user interface, so that learners can effectively solvequestions even on the terminal.

User Interface to Adjust Layer Size

Meanwhile, in the embodiment of FIG. 4, areas of the first layer 100 andthe second layer 200 are divided. Referring to another embodiment shownin FIGS. 7A and 7B, the second layer 200 may be overlaid on the firstlayer. That is, the first layer may be displayed on the entire screen,and the second layer 200 may be overlaid on one area of the first layer.

In this case, one area of the second layer may be designated as an areafor adjusting the size of the second layer, which may be displayed as animage 230 shown in FIG. 7A. When receiving a first touch input forselecting a portion (hereinafter, referred to as a scaling area) 230designated as a scaling area on the second layer from a learner andreceiving a continuous first touch gesture in the first touch input, theterminal may adjust the size of the second layer according to the touchgesture. For example, if the learner touches the scaling area and thendrags it upwards, the size of the second layer may become large, asshown in FIG. 7B. Such a user interface has an advantage in that a largeamount of text can be effectively displayed on a limited screen, andcontent displayed based on content currently checked by the learnerbetween text and question cards can be adjusted.

User Interface in Correct-Answer Confirmation Mode

Hereinafter, an embodiment of a method for displaying learning contentin the correct-answer confirmation mode after a learner completesquestion-solving and submits the answer will be described.

Referring to FIG. 5, when a learner selects a text or imagecorresponding to answer submission in operation S400, a terminalswitches to a correct-answer confirmation mode for displaying learningcontent using submitted answers in operation S430. An example of a userinterface in the correct-answer confirmation mode is shown in FIGS. 6Aand 6B.

As shown in FIGS. 6A and 6B, when a question card in which the submittedanswer is incorrect is displayed on the second layer in thecorrect-answer confirmation mode as shown in FIG. 6A, a terminal maydisplay a first layer and/or the second layer in a first color inoperation S470, and when a question card in which the submitted answeris correct is displayed on the second layer, the terminal may displaythe first layer and/or the second layer in a second color in operationS490. Here, the first color and the second color may be colors havingdifferent brightness and saturation, and a user interface according toan embodiment of the present disclosure may distinguish and displayincorrect answers and correct answers in an operation of confirmingcorrect answers so that learners may intuitively grasp their weaknesses.

In addition, on the screen of the correct-answer confirmation mode, whendisplaying the question card in which the submitted answer is theincorrect answer on the second layer, the terminal may differentlydisplay the brightness and/or the saturation of examples correspondingto the submitted answer and the correct answer.

For example, it is assumed that the correct answer of the question #5135B is “C. updating” as shown in FIG. 6B, and a learner selects “A.writing” as the answer and submits the selected answer in aquestion-solving operation. The terminal may provide a user interface inwhich the terminal differently displays the brightness and/or thesaturation of an answer 210A″ submitted by the learner and a correctanswer 210B″ so that the learner can compare the correct answer with theanswer input by herself or himself when confirming the correct answer.In this example, if the learner selects “C. updating”, only the correctanswer 210B′ may be highlighted, as shown in the screen of FIG. 6A.

Meanwhile, in the correct-answer confirmation mode, the learner confirmsthe correct answer to each of one or more questions that he or she hassolved. In this case, if an arbitrary question card is displayed on thesecond layer, the terminal may highlight one or more words correspondingto the arbitrary question card in text with a group of questionsdisplayed on the first layer. That is, when the learner confirms thecorrect answer to the question #5, as shown in FIGS. 6A and 6B, it ispossible to highlight the letters of the question #5 displayed in thetext, such as enlarging the letters, displaying the letters in bold, ordisplaying the letters in a different color, so that the learner canintuitively recognize exactly what the question he or she is checkingis.

In addition, in the correct-answer confirmation mode, the terminal maydisplay, on one area of the first layer, at least one of the time 150Brequired for question-solving, a text or image 170 corresponding toswitching to an explanation mode, and a text or image 160B correspondingto a termination command. As described above, the terminal may generatea new layer and include the above information in the new layer.

When the learner touches the text or image 170 corresponding to theswitching to the explanation mode, the terminal may switch the screen tothe explanation mode, and the user interface in the explanation modewill be described later with reference to FIGS. 7A and 7B.

In the explanation mode, the terminal may generate a third layer fixedin one area of the terminal and may display one or more question numbersand/or the text or image corresponding to the termination command on onearea of the third layer.

User Interface in Explanation Mode

Referring to FIGS. 7A and 7B, in the explanation mode, the terminal maygenerate a third layer fixed in one area of the terminal and may displayone or more question numbers 180 and/or a text or image 160Ccorresponding to a termination command on one area of the third layer.

-   -   The question number 180, displayed in a manner indicating that        question-solving is completed, may be displayed differently        depending on whether the submitted answer is correct or        incorrect. If the submitted answer is correct, the answer may be        displayed in a form shown in 180A. If the submitted answer is        incorrect, the answer may be displayed in a form including a        strikethrough. This is only an example, so the colors of the        correct answer and the incorrect answer can be displayed        differently or figures can be used, so that the learner can        intuitively distinguish a question for which a correct answer        was submitted by the learner from a question for which an        incorrect answer was submitted by the learner.

In addition, in displaying the question number 180, the terminal maydifferently display a question number corresponding to a question thatis currently confirmed. In this case, the terminal adds a point orinserts a figure on the question number as shown in 180A so that thelearner can intuitively recognize what the question number he or she ischecking is.

In the explanation mode, the configuration of the user interface foradjusting the size of the second layer may be effective. Since theexplanation includes not only examples but also a long text, the learnertouches one area of the second layer and inputs a touch gesturesuccessive thereto in operation S500, thereby moving an explanation carddisplayed on the second layer.

When the learner completes all of the learning and touches a learningcompletion button 160C displayed at the lower end side of the firstlayer, the screen of the terminal can be switched to an initial screenor the previous screen.

User Interface in Listening Mode

Hereinafter, a method for displaying learning content in a listeningmode according to an embodiment of the present disclosure will bedescribed with reference to FIGS. 8A and 8B.

Referring to FIGS. 8A and 8B, a terminal in the listening mode maydisplay a fourth layer 400 on a background layer 300 and may display oneor more question cards 400A to 400D on the fourth layer 400. Next, theterminal may sequentially reproduce one or more voice filescorresponding to each of the one or more question cards. At this time,if the question card corresponding to the currently reproduced voicefile is not displayed on the fourth layer, the terminal may displaymovement indicators 500A and 500B on the fifth layer 500.

More specifically, in displaying the movement indicators on the fifthlayer, when an arbitrary question card displayed on the fourth layer isa question previous to that of the question card corresponding to thecurrently reproduced voice file, the terminal may display the movementindicator at the lower end side of the fifth layer, as shown in 500A.When the arbitrary question card displayed on the fourth layer is aquestion subsequent to that of the question card corresponding to thecurrently reproduced voice file, the terminal may display the movementindicator at the upper end side of the fifth layer, as shown in 500B.

Further, when receiving a touch input for the movement indicator, theterminal may display the question card corresponding to the currentlyreproduced voice file on the fourth layer.

That is, if the currently reproduced voice file corresponds to thequestion #5 although questions displayed on the fourth layer 400 are aquestion #1 and a question #2 in FIG. 7A, a movement indicator 500A of“move to currently reproduced position” may be displayed at the lowerend side of the terminal, and if the learner touches the movementindicator 500A of “move to currently reproduced position”, the question#5 may be displayed at the central portion of the fourth layer.

In addition, if the currently reproduced voice file corresponds to thequestion #2 although a question #9 and a question #10 are displayed onthe fourth layer 400 in FIG. 7B, a movement indicator 500B may bedisplayed at the upper end side of the fifth layer 500. If the learnertouches the movement indicator 500B, the question displayed on thefourth layer may be switched to the question #2.

In addition, when the reproduction of the voice file corresponding toall of the questions is completed in the listening mode, or when acontinuous touch gesture (drag or the like) in a touch input is receivedso that the last question is displayed on the fourth layer, the terminalmay display the number of remaining questions at the lower end portionof the background layer using a selection input for each of thequestions, as shown in an image 600. That is, when the learner performsselection input for selecting examples for only two questions among atotal of 10 questions, 8, which is the number of remaining questions,may be displayed at the lower end portion based on the selection input.This display may be performed in such a manner that the image 600 can bedisplayed on the background layer 300 or the fourth layer 400 on whichthe corresponding question is displayed, or may be performed bygenerating a new layer.
